roblox is a knock off of minecraft. roblox is for people that do not have minecraft. minecraft can be bought on a ton of devices and you can only get roblox on mobile devices, and you can only play online.

Roblox was pre-beta in the year 1999-2004 And when 2004 came around it launched, while Minecraft's Beta launch was in the years of 2009-2010, Roblox was older and was intended to be singleplayer but instead took the route of a multiplayer game site, It was also free compared to the 20$ and up Minecraft in which is the same based style of the Singleplayer and Multiplayer but it also requires a ID. So In comparison Roblox is superior and if anything Minecraft was a rip off of roblox.
